Garbage, Glitter, or Gold: Assigning Multi-dimensional Quality Scores to Social Media Seeds for Web Archive Collections

TL;DR

This paper introduces a multi-dimensional scoring framework called Quality Proxies for assessing social media seeds used in web archiving, improving seed selection by considering credibility, relevance, and other factors.

Contribution

The paper presents the QP framework that assigns comprehensive quality scores to social media seeds, integrating social media credibility with web archive considerations.

Findings

Seeds scored with QP show increased precision (~0.13) in quality selection.

The framework is extensible and supports multiple ranking policies.

Quality scores are explainable and applicable across domains.

Abstract

From popular uprisings to pandemics, the Web is an essential source consulted by scientists and historians for reconstructing and studying past events. Unfortunately, the Web is plagued by reference rot which causes important Web resources to disappear. Web archive collections help reduce the costly effects of reference rot by saving Web resources that chronicle important stories/events before they disappear. These collections often begin with URLs called seeds, hand-selected by experts or scraped from social media. The quality of social media content varies widely, therefore, we propose a framework for assigning multi-dimensional quality scores to social media seeds for Web archive collections about stories and events. We leveraged contributions from social media research for attributing quality to social media content and users based on credibility, reputation, and influence. We combined these with additional contributions from the Web archive research that emphasizes the importance of considering geographical and temporal constraints when selecting seeds. Next, we developed the Quality Proxies (QP) framework which assigns seeds extracted from social media a quality score across 10 major dimensions: popularity, geographical, temporal, subject expert, retrievability, relevance, reputation, and scarcity. We instantiated the framework and showed that seeds can be scored across multiple QP classes that map to different policies for ranking seeds such as prioritizing seeds from local news, reputable and/or popular sources, etc. The QP framework is extensible and robust. Our results showed that Quality Proxies resulted in the selection of quality seeds with increased precision (by ~0.13) when novelty is and is not prioritized. These contributions provide an explainable score applicable to rank and select quality seeds for Web archive collections and other domains.
